Cause:
oo-admin-clear-pending-ops was missing a man page.
Consequence:
Administrators would not know how to use this tool without consulting the source.
Fix:
Man page added.
Result:
Better documentation.

Description of problem:
oo-admin-clear-pending-ops is described internally but not documented for our users.
Expected results:
man oo-admin-clear-pending-ops should tell us how to use it and what it's for.
oo-admin-clear-pending-ops -h should tell us what it's for.
Might be a good idea to mention it in the Troubleshooting Guide too.
